6.5. Inspecting, cleaning and replacing filters
Note
The ventilation unit comes with G3 filters as standard. These
filters are very suitable for use as "construction dust filters" after
initial completion of the dwelling. After around three months,
these filters should be replaced with G4 or F7 filters.
ä
Caution!
G4 and F7 filters can be cleaned once, after which they must be
replaced at the next maintenance interval.
Inspect and clean or replace the filters as follows:
a) Disconnect power to the ventilation unit.
b) Pull both filter caps out of the front panel.
c) Remove the filters from the ventilation unit. There are tabs at
the front of the filters for this purpose.
d) Visually inspect the filters for soiling. If the filters are dirty, they
must be cleaned or replaced.
e) Clean or replace the filters. To clean the filters, gently tap them
to remove the dirt or use a vacuum cleaner.
f)
Insert the cleaned filters or new filters in the ventilation unit.
